A game must have a Metacritic score to show, unless it is multiplatform

The definition of Exclusivity is as follows:

Exclusive: The game can be played on that platform only, and no other. For example a game that can only be played on the Wii U

System Exclusive: The game can be played on that platform and any sibling devices of that platform's manufacturer. For example, a PS4 game that can also be played on the PS3 or PS Vita

Console Exclusive: The game can be played on that platform, any siblling devices of that platform's manufacturer, as as well as on PC or Mobile. For example, a Xbox One game that is also available on the Xbox 360 and PC

HD Remakes, of any description, will never be considered as true exclusives

DLC does not count unless:

it has a retail release - for example Diablo 3 : Reaper of Souls

or it is standalone and does not need the original to play - for example inFamous First Light

or it is episodic title that does not have a full version release

Retail Games are determined from the release data at GameFaqs. Only U.S Retail information is considered.

First Party Published Games are any Console Exclusive games that meet the following criteria:

PC: The PC cannot have first party games since its hardware is not wholly owned by one entity.

PC Games start counting from November 2013, the same release date as the PS4 & Xbox One
